Genus Ibiceps. 

 Ibiceps Buckt. Mon. Merabrac. p. 238 (1903). 

 Buckton has not denoted his type and has included some heterogeneous species under 

 his generic name. His first species enumerated is faloatus Walk, (described under 

 that name as a new species). But this species was previously used by Goding as the 

 type of his genus JEiifrenchia (1903), while Stal for Sertorius (1866), first described 

 S. curv/cornis (1869), which is a synonym of Gentrotus faloatus Walk. To prevent 

 further confusion I propose /. ansatus Buckt. (a synonym of altioeps Walk.) as the 

 type of his genus Ihiceps.
